I vaguely remember reading about some supposed advantages of launching very large rockets (Saturn size and larger) from underwater in an ocean or similar large body of water. I was recently reminded of this by a short scene in a popular show (no spoilers) showing a rocket larger than Saturn emerging from the sea in a fiery launch.
What are the advantages of a submerged launch, if any? Has any serious work been done in this area? Or is this idea just imaginative science fiction?
The show…
is: For All Mankind on Apple TV+, last episode of Season 1, past the closing credits.
